If your goal is bra strap length hair, then don't cut it into a layered style.
My stylist cut my hair into layers after my virgin relaxer in April. He calls them "long layers" when I remind him that I'm going to grow them out. My mom likes the layers too, but I don't.
My hair is very fine, and the layers are visible when I wear it airdried curly, but not so much when it's rollerset straight. The shortest layers that frame my face aren't long enough to tuck into a bun or claw when I want all the hair up and out of my way, so I have to pin them up separately. I find this mildly annoying.
I'm going for the total Xmas tree pyramid shape ALL the way down to my shoulders when I wear the ringlets down (see the model in my Pics link), not this inverted stair step thing I've got going now.
